摘　　要：为统一地层认识和划分方案,根据层序地层学理论,结合地层厚度的发育特征、古生物特征,综合应用标志层、断块内密井网-断块间标准井对比及井震结合等方法,对欧利坨子地区S3上亚段地层进行划分与对比.结果表明,S3上亚段地层可划分为4个油层组、11个砂岩组和19个小层.此划分方案在油田生产实践中取得了较好的应用效果.To unify the recognition and classification of stratigraphy,guided by the theory of sequence stratigraphy,combined with the development characteristics of stratum thickness and paleobiology feature of stratum,some methods such as the key bed method,the logging-seismic combination analysis method and the correlation of dense well pattern in fault-block and standard well pattern among fault-blocks method are comprehensively developed to classify and correlate the upper section stratum of the Eogene system Sha_3 in Olituozi area.The conclusion is that the upper section stratum can be divided into 4 oil layer groups,11 sandstone groups and 19 substrata.And the correlation result are proved to be effective for the development.
